Abstract
The invention discloses monocomponent PRTV anti-pollution-flashover paint and a preparation method thereof. The monocomponent PRTV anti-pollution-flashover paint is composed of the following materials in parts by weight: 28-38 parts of polydimethylsiloxane, 10-19 parts of hydroxyl-terminated fluorine-containing polysiloxane, 3-5 parts of nanometer silica, 1-3 parts of a coupling agent, 0.5-1 part of a catalyst, 2-3 parts of decabromodiphenyl ether, 1-2 parts of a pigment and 40-50 parts of a solvent. The monocomponent PRTV anti-pollution-flashover paint has the beneficial effects that a fluorine material and a nanometer material are organically combined and blended with silicone rubber, silicone rubber is taken as main base rubber and fluorosilicone rubber is taken as auxiliary base rubber; and the monocomponent PRTV anti-pollution-flashover paint has the main technical advantages of being good in flame retardant effect, substantially reduced in cost.
Description
Technical field
The present invention relates to insulating material production technical field, specifically a kind of single component PRTV antifouling flush paint and preparation method thereof.
Background technology
The electric installation of outdoor layout is easily subject to the impact of environment, its dielectric level easily reduces and causes electric insulation fault under extreme case, therefore, how to improve outdoor electrical equipment insulation the adaptability of environment is just become to one of problem of maintenance of electric device personnel concern.Certainly, the design phase with regard to consider the residing atmospheric environment of electric installation and pointedly selection equipment be the problem that first will consider, but along with the apparatus insulated level of growth of equipment investment working time can aging to some extent reduction, and equipment environment of living in also can change, and all promote measure and product that novel raising is apparatus insulated to obtain increasingly extensive application for these factors such as pursuit of raising the efficiency reduction labour intensity.
And existing RTV antifouling flush paint, be exactly occur in recent years a kind of for improving the novel material of insulation of electrical installation level, be 5 years the work-ing life of initial RTV coating, progress along with technology, the further raising of product performance, also brought up to 10 years work-ing life, but this has reached the ultimate life of RTV coating.In order further to improve the work-ing life of antifouling flush paint, improve its over-all properties, make it there is oil repellency and self-cleaning, need new insulating material substitute badly.
Summary of the invention
For addressing the above problem, the invention provides a kind of single component PRTV antifouling flush paint and preparation method thereof, PRTV antifouling flush paint has hydrophobicity and the migration of hydrophobicity that is better than RTV antifouling flush paint, has good oil repellency and non-viscosity simultaneously.
The technical solution adopted for the present invention to solve the technical problems is,
This single component PRTV antifouling flush paint is comprised of the material of following weight part:
Polydimethylsiloxane: 28-38;
Terminal hydroxy group fluorinated polysiloxane: 10-19;
Nano silicon: 3-5;
Linking agent: 1-3;
Catalyzer: 0.5-1;
Decabromodiphenyl oxide: 2-3;
Pigment: 1-2;
Solvent: 40-50;
Described polydimethylsiloxane is silicon rubber;
Described terminal hydroxy group fluorinated polysiloxane is trifluoropropyl siloxane, and viscosity is 1200-2000cp;
Described catalyzer is stannous octoate;
Described pigment is red iron oxide or titanium dioxide;
Described solvent is mc-318 double solvents, not containing Ozone Depleting Substances ODS composition.
The preparation method of this single component PRTV antifouling flush paint:
(1) polydimethylsiloxane, terminal hydroxy group fluorinated polysiloxane, nano silicon and pigment are sent in star formula agitator and are uniformly mixed 1.8-2.2 hour according to weight part respectively, temperature is controlled at 140 ℃-160 ℃;
(2) high vacuum is isolated the low molecular compound after chemical reaction, then cooling;
(3) cooling completing by three rollers ground;
(4) according to weight part, add linking agent, catalyzer, decabromodiphenyl oxide and solvent, after mixing in star formula agitator, under nitrogen protection, filter, pack in the metal bucket of isolated air.
The beneficial effect that the present invention produces is: this single component PRTV antifouling flush paint be fluorine material and nano material organically in conjunction with and be compound in silicon rubber body, silicon rubber is main base glue, fluorine silica gel is auxiliary base glue.Through test of many times, PRTV coating can increase substantially electric power power transmission and transformation equipment outer insulation pollution flashover voltage, can make it bring up to 200%, ensures power equipment operating safety; Have hydrophobic nature and unique hydrophobic nature migrate attribute, hydrophobic nature can migrate to pollution layer surface, at severe weather (rain, mist dew, drizzling rain) coatingsurface, does not form continuous moisture film; Coating surface has hydrophobic nature, thereby has effectively prevented that cement and chemical industry filth are at its surface scale, thereby can be widely used in various natural, industrial environments.Its excellent insulation performance, mechanical property are good, strong adhesion, anti-dust adhere to, corrosion-resistant, the life-span long, resistance to corona, ageing-resistant, and have good anti-shoe ice effect and good weather resisteant; This coating does not fire, and solidifying afterfire grade is FV-0 level, and non-poisonous substances, has special odor; In the time of this product good flame retardation effect, can significantly reduce costs is again the major technique advantage of this coating of invention.
